【摘要】 本文较系统地讨论了虚反射的理论时距曲线、信息的采集、解释及对地震信号的频率响应，虚反射会影响地震资料的分辨率，为克服其影响，进行了不同激发深度的实际试验。说明了选取最佳激发深度的工作方法技术。更多还原

【Abstract】 In the paper, the theoretical time-distance curves, information acquisition, interpretation, and frequency response of ghost reflection are discussed systematically. The ghost can influence the resolution of seismic data. In order to overcome the influence, practical tests have been conducted for different excitation depthes. The methdritw for edecting the optimum excitation depth is given.更多还原
